4. 1 CORE NETWORK
Objectives
• Grasp Basic Idea Of GSM System Such As Frequency Spectrum,
Frequency Reuse etc.
• Grasp The Structure Of GSM System And The Protocol Used
• Grasp Certain Numbers That Refer To BSS
• Grasp the 4 Kinds Of Channel Combination And Understand The Idea
Of Multiframe
• Know Some Radio Techniques
• Get The Idea Of EDGE.

5. GSM SYSTEM OVERVIEW
• The GSM system is a frequency- and time-division cellular
system, each physical channel is characterized by a carrier
frequency and a time slot number
• Cellular systems are designed to operate with groups of low-
power radios spread out over the geographical service area.
Each group of radios serve MSs presently located near them.
The area served by each group of radios is called a CELL
• Data for different users is conveyed in time intervals called
slots , several slots make up a frame. This kind of technique is
called Time Division Multiple Access (TDMA)

6. GSM DEVELOPMENT
Standard Protocol for GSM take effect
System was named as Global System for
Mobile Communication
GSM system began to provide service in Europe(2G)
Provide services for the whole world
Micro Cell Technique is used in GSM system
1989
1991
1992
1994
1996

7. MULTIPLE ACCESS
TECHNIQUE
• Multiple Access Technique allows many subscribers to use the
same communication medium.
• There are three kinds of basic Multiple Access Technique :
FDMA , TDMA and CDMA.
• GSM system adopt FDD-TDMA (FDMA and TDMA together).

8. FREQUENCY REUSE
• The frequency resource of mobile system is very limited.
• The different Subscribers can use the same frequency in
different places.
• The quality of communication must be ensured

The Physical Channel is the medium over which the
information is carried: 200 KHz and 0.577 ms.
The Logical Channel consist of the information carried over

14. 2 DATA COMMUNICATION
FUNDAMENTALS
OBJECTIVES
• Overview of Network Fundamental
• Basic Routing Principle
• Basic Switching Principle
• Overview Of Access Network
• GPON Network Architecture
• GPON Protocol Analysis
• Datacom Product Overview

15. OSI REFERENCE MODEL
• In 1984 in order to aid network interconnection without
necessarily requiring complete redesign, the Open Systems
Interconnection (OSI) reference model was approved as an
international standard for communications architecture.
• The Open Systems Interconnection (OSI) reference model is a
descriptive network scheme. It ensures greater compatibility
and interoperability between various types of network
technologies.
• The OSI model describes how information or data makes its
way from application programmes (such as spreadsheets)
through a network medium (such as wire) to another
application programme located on another network.

16. WHY 7 LAYERS ?
In 1983, Day and Zimmerman laid down certain principles that were applied to
arrive at the seven layers can be briefly summarized as follows:
• A layer should be created where a different abstraction is needed.
• Each layer should perform a well-defined function.
• The function of each layer should be chosen with an eye toward defining
internationally standardized protocols.
• The layer boundaries should be chosen to minimize the information flow across
the interfaces.
• The number of layers should be large enough that distinct functions need not be
thrown together in the same layer out of necessity and small enough that the
architecture does not become unwieldy

17. OSI MODEL

18. TCP/IP REFERENCE MODEL
The Internet Protocol Suite (commonly known
as TCP/IP) is the set of communications
protocols used for the Internet and other similar
networks.
It is named from two of the most important
protocols in it:
The Transmission Control Protocol (TCP)
The Internet Protocol (IP), which were the first two
networking protocols defined in this standard.

21. 3 CLOUD COMPUTING
OBJECTIVES
• Introduction To Typical IT Environment
• Cloud Concept
• Deployment Models
• Understanding On Huawei Desktop Cloud

22. INTRODUCTION
• Cloud computing is a type of computing that relies
on sharing computing resources rather than having local
servers or personal devices to handle applications.
• In cloud computing, the word cloud (also phrased as "the
cloud") is used as a metaphor for "the Internet," so the
phrase cloud computing means "a type of Internet-based
computing," where different services such as servers,
storage and applications are delivered to an organization's
computers and devices through the Internet

23. CLOUD SERVICE MODELS
There are mainly 3 service models given as:
1. Software as a Service (SaaS)
2. Platform as a Service (PaaS)
3. Infrastructure as a Service (IaaS)
